LV8731V: Stepper Motor Driver, PWM, Constant Current Control

Datasheet: PWM Constant-Current Control Stepper Motor Driver
Rev. 5 (306kB)
Product Overview
»View Material Composition
» Product Change Notification
The LV8731V is a 2-channel H-bridge driver IC that can switch a stepper motor driver, which is capable of micro-step drive and supports 4W 1-2 phase excitation, and two channels of a brushed motor driver, which supports forward, reverse, brake, and standby of a motor. It is ideally suited for driving brushed DC motors and stepper motors used in office equipment and amusement applications.
Features   Benefits
     
  • Low on resistance (upper side : 0.3Ω; lower side : 0.25Ω; total of upper and lower : 0.55Ω; Ta = 25°C, IO = 2A)
 
  • High Efficiency
  • Excitation mode can be set to 2-phase, 1-2 phase, W1-2 phase , or 4W1-2 phase
 
  • Various Step Adjustment Available
  • Motor current selectable in four steps
 
  • Low Consumption
  • Output short-circuit protection circuit (selectable from latch-type or auto-reset-type) incorporated
 
  • Safety Design
  • No control power supply required
 
  • Easy Design
  • CLK-IN Input
 
  • Easy Control for Micro-step Drive
  • Single-channel PWM current control stepper motor driver (selectable with DC motor driver channel 2) incorporated.
   
  • BiCDMOS process IC
   
  • Excitation step proceeds only by step signal input
   
  • Unusual condition warning output pins
